Abstract: 

Epileptic activity in the brain can affect language development in children, and EEG registrations should therefore be carried out more frequently on children with severe language impairment to identify more readily those who may need medical treatment, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg.

Abstract: 

New research finds that the brains of infants as young as 7 months old demonstrate a sensitivity to the human voice and to emotions communicated through the voice that is remarkably similar to what is observed in the brains of adults.

Abstract: 

At a Feb. 20 press briefing held during the American Association for the Advancement of Science annual meeting, a Northwestern University neuroscientist argued that music training has profound effects that shape the sensory system and should be a mainstay of K-12 education. Kraus presented her own research and the research of other neuroscientists suggesting music education can be an effective strategy in helping typically developing children as well as children with developmental dyslexia or autism more accurately encode speech.

Autism is a genetically complex neurodevelopmental syndrome in which language deficits are a core feature. We describe results from two complimentary approaches used to identify risk variants on chromosome 7 that likely contribute to the etiology of autism. A two-stage association study tested 2758 SNPs across a 10 Mb 7q35 language-related autism QTL in AGRE (Autism Genetic Resource Exchange) trios and found significant association with Contactin Associated Protein-Like 2 (CNTNAP2), a strong a priori candidate. Male-only containing families were identified as primarily responsible for this association signal, consistent with the strong male affection bias in ASD and other language-based disorders. Gene-expression analyses in developing human brain further identified CNTNAP2 as enriched in circuits important for language development. Together, these results provide convergent evidence for involvement of CNTNAP2, a Neurexin family member, in autism, and demonstrate a connection between genetic risk for autism and specific brain structures.

Infant and Toddler Oral and Manual Motor Skills Predict Later Speech Fluency in Autism

Infant and toddler oral-motor and manual-motor skills inter-correlated significantly, distinguished autistic children from typically developing children, and distinguished autistic children whose current-day speech was minimally fluent, moderately fluent, and highly fluent. These results were corroborated by analysis of historical home video and verified with current-day assessment.
